Acute biliary pancreatitis: Staging and management

Background/Aims: Acute biliary pancreatitis is a clinical entity with a high morbidity rate (15-50%) and mortality rate (20-35%). Early diagnosis has a primary importance for an appropriate treatment (75% of cases of idiopathic acute pancreatitis are of biliary origin). Methodology: Diagnosis of acute biliary pancreatitis in 78 patients was based on careful clinical and instrumental assessment: ultrasonography (76.9% of cases) and laboratory tests in 23.1% of cases. In our study we used the Ranson and APACHE II scores and 24 of the cases (30.7%) were classified as severe, while 54 (69.2%) were mild. All patients with severe acute biliary pancreatitis underwent emergency endoscopic retrograde cholangiopancreatography + endoscopic sphincterotomy (within 24-48 hours) followed by laparoscopic cholecystectomy (10 days). Patients with mild acute biliary pancreatitis underwent laparoscopic cholecystectomy associated with intraoperative cholangiography, within 10 days. Results: In 19 patients with severe acute biliary pancreatitis operative endoscopy was curative. Subsequent laparoscopic cholecystectomy provoked subcutaneous emphysema only in one case but did not show any other serious morbidity. In the remaining 5 cases laparotomy was required because of necrosis, with a mortality rate of 60%. In all cases of mild acute biliary pancreatitis, laparoscopic cholecystectomy was successfully performed with a morbidity rate of 7.3%. Common bile duct stones were revealed with intraoperative cholangiography in 31.4% of the mild cases and in 75% of the severe cases. Conclusions: In conclusion acute biliary pancreatitis treatment is always surgical; in almost all severe cases it is performed with minimally invasive procedures (endoscopic retrograde cholangiopancreatography + endoscopic sphincterotomy with laparoscopic cholecystectomy less than or equal to 10 days) if surgery is carried out within 24-48 hrs, as well in the mild cases (laparoscopic cholecystectomy + intraoperative cholangiography) when surgery is performed within 10 days.
